#include "CoreMinimal.h" #include "SomeObject.h" TWeakObjectPtrIn this example, we declare a TWeakObjectPtr called `WeakObject` that refers to an instance of the `USomeObject` class. We then define two functions: `SetWeakObject` and `UseWeakObject`. The `SetWeakObject` function takes a pointer to a `USomeObject` instance and sets the `WeakObject` pointer to hold a weak reference to it. The `UseWeakObject` function checks if the weak reference is still valid before using the object. This is important because weak references do not keep the referenced object alive, so it may be destroyed at any time. Overall, TWeakObjectPtr is a useful class for managing weak references in the Unreal Engine 4, and can help prevent memory leaks and access violations in your code.WeakObject; void SetWeakObject(USomeObject* Object) { WeakObject = Object; } void UseWeakObject() { if (WeakObject.IsValid()) { // Use the weak object } }
